SPOKE-FORMING DEVICE.

Specification of Letters Patent.

Application filed September 24, 1a21. Serial no. 502,873.

T 0 all whom it may concern:

Be it known that WILLIA MoCULLoUeH, a citizen of the United States, residing at Howe, in the county of: Nemaha and State of Nebraska, has invented certain new and useful Improvements in Spoke-Forming Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to spoke shaping devices, and has for its object to provide a device of this character comprising a horizontally disposed member having rotatably and slidably mounted therein a horizontally disposed cutter carrying chair having a crank at one end thereof, said horizontally disposed member being provided with a reduced portion, on which reduced portion a. spoke holding member is mounted and adjustably held in axial alignment whereby the spoke carried thereby will be axially held in relation to the rotatably and slidably mounted cutter carrying chair.

A further object is to provide a horizontally disposed toothed rack extending outw-ar dly from the horizontally disposed memher and with which rack a lever engages, which lever is provided with a bifurcation, the arms of'which are moved on opposite sides of therotatable shaft and engage 'a collar thereon, and forms means for feeding the rotatable and slidable shaft during a spoke cutting operation.

' With the above and other objecm in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a side elevation of the device.

Figure 2 is a top plan view.

Figure 3 is a vertical longitudinal sectional view through the device taken on line 83 of Figure 2.

Figure 4; is a detailed perspective view of the feeding lever and a portion of the cutter shaft.

shaping operation. with a reduced portion 5, which reduced Figure 5 is a detail sectional viewtaken on line 5-5 of Figure 4.

Referring to the drawings, the numeral 1 designates an elongated body memberhorizontally disposed and 2 a rotatably and slidin bearings 3 of arms 4 of the member .1 and is horizontally disposed. The member 1 may be supported in any suitable manner and held against movement during'a spoke Member 1- is provided portion forms shoulders 6, and on said reduced portion is vertically. slidable a spoke supporting member 7,. said member 7 00mprising spaced U-shaped members-8 and 9, whlch U-shaped members have oneof their arms disposed on 'eachjside of the reduced portion 5', and are connected together by the horizontally disposed bars '10 located on each side of the reduced portion 5. The outer end ofthe reduced portion 5 terminates in washer13and forces the same into fric- Paten ted Aug, 15, 1922.

ably mounted cutter shaft, which is mounted 1 a threaded portion 11, onwhich portion is threaded a thumb nut 12, which engages ational and binding engagement with the outer side of the U-shaped' member'9, and

the. forward edge of the U shaped member.

8 into frictional and binding engagement wlth the shoulders 6 of the member- 1, thereby holding the supporting member 7 in various vertical positions. To additionally hold the supporting member. 7, the reduced portion 5 of the member 1 is provided with a vertically disposed threaded shaft 14, which shaft extends upwardly througl'i an aperture in the transverse portion of the U-shaped member 8, and has threaded, thereon a thumb nut 16, which thumb nut and threaded shaft 14 forms means for. accurately gaging the position of the supporting member 7 and holding said supporting member until it is securely clamped by the thumb nut12 and washer 13. Secured between the lower ends of the arms of the U-shaped members 8 and 9 are notched blocks 17, in the notches 18 of which a coni ventional form of spoke 19 isheld by means of a vertically movable notched block 20, which blockis mounted between arms 21 of a U-shaped member 22, which member arches operator grasps the handle 26,

with his right hand, and with his left hand spoke 19 has been placed in position that the spoke 19 may be accurately positioned in axial alignment with the rotatable and slidable cutter shaft 2 so that when the shaft 2 is rotated by means of the handle 26 and forced in the direction of arrow 5!, the cutter '27 will form the tenon 19 on the end of the spoke 19, thereby accurately positioning the tenon 19 in relation to the axis of the spoke l9 and forming the same quickly at a minimum cost and with a minimum loss of time.

During the rotation of the shaft 9 it will be necessary for the shaft 2 to move in the direction of the arrow (4 in its bearings 26. To accomplish this result during the rotating operation a lever 28 is provided, which lever is provided with a bifurcation 29 which receives the shaft 2 in such a manner that the arms 30 of the lever will engage an adjustably mounted collar 31 carried by the shaft 2. 'Lever 28 is provided with a downwardlye xtending lip 32, which lip engages one of the teeth 33 ot' a horizontally disposed toothed rack 3%, which rack extends outwardly from the downwardly extending; arms i of the member 1. In operation the preferably he grasps the outer end 35 of the lever 28 and forces the same in the direction of the arrow Z), which action will cause the shaft 2 to feed in the direction of the. arrow a during a spok shaping operation. The device may be supported in any suitable manner, however for purposes of illustration an out wardly extending arm 36 is shown, which arm may be supported in any suitable maunor, for instance in a vice, however it is to be understood that the device may be supported in any suitable manner.

From the above it will be seen that a spoke shaping device is provided which ter shaft and means for feeding said c' is simple in construction, easily adjusted and one which may be operated by a single person.

The invention having been set forth what claimed as new and useful is 1. T he combination with a horizontally disposed member having a spoke cutter shalt rotatably and slidably mounted in bearings thereof, of a spoke supporting member therefor, said supporting member being mounted on a reduced portion otthe horizontally disposed member and vertically slidable thereon in engagement with shoulders formed by the reduced portion, the outer end of the reduced portion being threaded, nut threaded on said reduced aortic-n and adapted to force the spolre supporti mem her in engagement with the shoulders formed by the reduced portion, a threaded member extending upwa dly through the spoke supporting n inber provided with a nut for feedino; the spoke siiipporting member downwardly for accurately gaging the po sition of spoke in relation to the cutter shaft, a handle member carried by said cuttter shaft in the direction of the spoke during; a spoke cuttin peration. 7

2. A spoke t main body member, ahorizontally disposed rotatable and longitudinally movable cut-- ter carryi shaft carried by the body member, a vei really adjustable spoke carrying ling machine comp""sin, a '7 member mounted on a reduced portion of the body member, shoulders carried by said body member, means for forcing said spolre carrying; member into engagement with said shoulders, means for clamping a spoke in said i-apoire carrying member in axial alignn with the cutter carrying shaft, anoperatin crank tor said cutter shaft, a collar a liustably mounted on said shaft, a feeding 1' provided with a bifurcation in which shaft is received, the arms formed by said bifurcation engaging the adjustable collar, a toothed rack disposed below said operatino' lever and a downwardly extending tooth carried by said lever and adapted to "rage one of the teeth of the toothed rack vreby the cuttershaft maybe moved. longitiulinally.

in testimoi'iy whereof I hereunto ailix my mature.
